Abstract

In at least one example, an optical component includes a central optical surface proximate an optical axis, a peripheral portion extending radially from the central optical surface, and a stepped portion between the central optical surface and the peripheral portion. The stepped portion may be formed to raise the central optical surface above the peripheral portion.
